About this app:

Refresh Rate Mods
  • Change default refresh rates
    -Easily change the overall refresh rate settings of devices supporting multiple refresh rates.
    -Set supported mid refresh rates as the maximum refresh rate limit for battery savings (e.g. 96hz instead of 120Hz).
    -Quick settings shortcut
    -Tasker plugin support

    Note: It's reported that after a certain Samsung's update, 96Hz on Adaptive Mode doesn't anymore work on S22 while on normal power mode. But still working while on power saving mode on certain brightness level. Unfortunately, this is beyond control of GMH.


  • Motion smoothness mode switcher(Normal, Adaptive or High)***
    -Set you device motion smoothness mode to stationary refresh rates (high mode) for better smoothness if so desired on Samsung devices with native Adaptive motion smoothness with a little trade-off to the battery.
    -Apply adaptive mod on device that don't natively support adaptive mode [premium]
    -Tasker plugin support

  • Per-app refresh rate settings:
    Set different refresh rate settings for every app either adaptive or fixed(stationary) [premium].

  • Motion smoothness on power saving mode (not working to all devices with OneUI4.**+, test first). ***
    -GMH will apply a workaround to bypass 60Hz limitation on Power Saving Mode (PSM) on supported Samsung smartphones.
    -Automatically apply workaround when PSM is enabled [premium]

    Note: It's reported that this workaround is blocked and not working in OneUi5.0 on S22
Screen-off Mods:
  • Force to Lowest Hz
    -Force the lowest refresh rate on screen-off or Always-On Display(AOD) to improve standby power consumption a bit.
    -Select refresh rate to set for AOD/screen-off[premium]
    -Tasker plugin support.

  • Auto apply power saving mode during screen-off ***


  • Auto disable Autosync***


  • Quick-doze mod
    -
    Quickly enter doze mode during screen-off that can not be interrupted by motion [premium]***
    -Tasker plugin support

  • Auto SENSORS OFF (experimental non-root workaround)
    -Device sensors will automatically turn off while screen is off until the device is unlocked to help minimize battery-draining motion-triggered wakelocks while device is not being used [premium]
    -Tasker plug-in support
    - Supports up to OneUI4.* only
Others
  • Battery protection mod (Experimental)
    -Option to set maximum charge to 86%-95%(for OneUI4+)[premium]


  • Quick resolution switcher
    -Easily switch to any supported resolutions using the included quick setting tile***
    -Tasker plugin support


  • Customizable refresh rate monitor
    -
    Use statusbar or overlay which you can place anywhere on screen.
    -Tasker plugin support

  • Net speed statusbar indicator
OneUI inspired UI. Dynamic theme and Icon. Manual language selection

Note: The premium license is on a per device basis (not per user).


***these marked features require a one-time ADB procedure (this is not root)

Galaxy Max Hz background service is highly optimized. Background battery usage p is very negligible .

Info:
This app targets older android sdk in order to control refresh rates without ADB setup or root. Just tap OK the dialog that says "This app was built for an older version of Android...." when opened for the first time. If OK button is not visible, just tap the blank space on the lowest portion of the dialog.

If google play protect will prompt during install that the app is built for older version of android and doesn't include the latest privacy protections, you can ignore it and proceed to the installation. For privacy related concern, please refer to FAQ No. 3.

S22 SD variant here, I can confirm
96hz does not work when set as Min/Max (will default to 60hz)
48hz does not work when set as Min/Max (will default to 30hz)

Other than that, Great job. I can see myself getting premium.

I am still on Jan Security Patch, The March update will take awhile before coming to my country if there is even one for SD variant. I know there a Exynos Update that all
Strange. S22 is advertized to support 48hz.
May I know the lowest refresh rate S22 normally goes down on stock (when galaxy max hz is not installed)? Thank you

Same here with Snapdragon variant, seems to just drop it down to 60 according to refresh rate overlay in Developer settings.
S22 SD, 96Hz adaptive doesn't work. It will switch between 24Hz and 60Hz....However, setting Max Hz to HIGH 96Hz works but will keep 96Hz as fixed.

Samsung Galaxy S22
I brought the premium version of galaxy hz for my s20 a while ago, could I somehow migrate the license to my s22, like deactivating s20 version and enabling it on my s22?

96Hz works again after the latest update.
And after 3 hours it doesn't work, again.

Hello, for to get more lower frequencies ( 30-48 mhz) i have to disable the battery saver ( when i place this battery saver option the screen is placed to 60 mhz by default), can you fix this? thanks

    I respect your opinion. But it's not that easy. Basically this feature is just exploiting a bug on the system and that bug was already patched.
    Ah OK didn't realise that. Sorry hope I didn't come across too rude, just frustrated was all.
